'Worst' Airline Passengers Ever?

What is it about air travel that makes people act foolish? Is it the confined space? The too-small seats? The person in the seat next to you who insists on hogging the armrest? Whatever drives you crazy on an airplane, hopefully it hasn't driven you over the edge. Unlike the following five people who may just be the worst airline passengers ever.

An American Airlines flight was forced to make an emergency landing last week when a female passenger refused to stop singing Whitney Houston songs. AA Flight 4 was en route from Los Angles to New York's John F. Kennedy International Airport on May 9 when, according to the airline, the flight was diverted to Kansas City because of a "very unruly passenger."

A video of the woman being escorted off the plane is available on the website of local television station KCTV. It shows the woman belting out "I Will Always Love You" as at least two uniformed officers accompanied her off the plane.

Joe Hundley, a 60-year-old-man traveling from Minneapolis to Atlanta, was accused of slapping a 19-month-old boy and telling his mother to "shut that n-word baby up." The toddler's mother, Jessica Bennett, told ABC News her son's eye was swollen and bleeding and she was "scared to death."

Hundley, who was employed as an executive at AGC Aerospace and Defense, lost his job. He pleaded not guilty to simple assault charges in a federal court.

A man on a January Icelandair flight was so drunk and belligerent, passengers said, that he had to be restrained with duct tape. The unidentified passenger allegedly downed an entire bottle of duty-free alcohol, according to a man who posted the photo of the duct-taped man on his blog. The airline accused the man of accosting and hitting people on the flight. Passengers say he even tried to choke the person next to him and screamed, "The plane is going to crash."

Two reportedly drunk women forced the landing of a British Airways flight in Lyon, France, in late 2012. Flight BA2664 was headed from London's Gatwick Airport to Tunis. The flight was diverted to Lyon, the airline said, following "the continued disruptive behavior of two female passengers."

British tabloid The Sun reported the women were drinking Malibu rum and swore at children. They reportedly threatened the family of a British Airways flight attendant and tried to storm the cockpit and hid in the lavatory and tried to smoke.

The paper quoted a passenger as saying, "They decided they were going to meet the captain and marched towards the cockpit. It was very frightening."

A woman stripped naked at Denver International Airport last year after being caught smoking in a non-smoking section of the airport. Airport spokeswoman Jenny Schiavone said it appeared the woman had some sort of a breakdown and the disrobing didn't have anything to do with the smoking ban.
